Filamet(TM) metal-infused filament with Bronze, Copper (soon Brass, Nickel-Silver?) for producing high-density metal objects, sintered in a kiln, after being printed on a cheap, run-of-the-mill FDM printer. Wondering about shrinkage/deformation from heating, but this sounds promising for non-m/billionaires.

At scales to be at all relevant, say, 12" cube width and above, plain old machining is practical and cheap. Porous, sintered messes based on plastics will be dimensionally unstable and a horror show under vacuum.
